 SASjs is a open-source framework for building Web Apps on SAS® platforms. You can use as much or as little of it as you like. This repository contains the JS adapter, the part that handles the to/from SAS communication on the client side. There are 3 ways to install it:
 
 1 - `npm install @sasjs/adapter` - for use in a nodeJS project (recommended)
 
-2 - [Download](https://cdn.jsdelivr.net/npm/@sasjs/adapter@3/index.min.js) and use a copy of the latest JS file

 The following code will instantiate an instance of the adapter:
 
 ```javascript
-let sasJs = new SASjs.default(

-    serverType:"SAS9"
-  }
-);

 ```js
-  import SASjs from '@sasjs/adapter';

 ### SAS Logon
-All authentication from the adapter is done against SASLogon.  There are two approaches that can be taken, which are configured using the `loginMechanism` attribute of the sasJs config object (above):
 
-* `loginMechanism:'Redirected'` - this approach enables authentication through a SASLogon window, supporting complex authentication flows (such as 2FA) and avoids the need to handle passwords in the application itself.  The styling of the window can be modified using CSS.
-* `loginMechanism:'Default'` - this approach requires that the username and password are captured, and used within the `.login()` method.  This can be helpful for development, or automated testing.
+All authentication from the adapter is done against SASLogon. There are two approaches that can be taken, which are configured using the `loginMechanism` attribute of the sasJs config object (above):
+
+- `loginMechanism:'Redirected'` - this approach enables authentication through a SASLogon window, supporting complex authentication flows (such as 2FA) and avoids the need to handle passwords in the application itself. The styling of the window can be modified using CSS.
+- `loginMechanism:'Default'` - this approach requires that the username and password are captured, and used within the `.login()` method. This can be helpful for development, or automated testing.

-###  Request / Response
+### Request / Response
+
 A simple request can be sent to SAS in the following fashion:
 
 ```javascript
-sasJs.request("/path/to/my/service", dataObject)
-  .then((response) => {
-    // all tables are in the response object, eg:
-    console.log(response.tablewith2cols1row[0].COL1.value)
-  })
+sasJs.request('/path/to/my/service', dataObject).then((response) => {
+  // all tables are in the response object, eg:
+  console.log(response.tablewith2cols1row[0].COL1.value)
+})
 ```
 
 We supply the path to the SAS service, and a data object.
 
-If the path starts with a `/` then it should be a full path to the service.  If there is no leading `/` then it is relative to the `appLoc`.
+If the path starts with a `/` then it should be a full path to the service. If there is no leading `/` then it is relative to the `appLoc`.
 
 The data object can be null (for services with no input), or can contain one or more "tables" in the following format:
 
 ```javascript
-let dataObject={
-	"tablewith2cols1row": [{
-		"col1": "val1",
-		"col2": 42
-	}],
-	"tablewith1col2rows": [{
-		"col": "row1"
-	}, {
-		"col": "row2"
-	}]
-};
+let dataObject = {
+  tablewith2cols1row: [
+    {
+      col1: 'val1',
+      col2: 42
+    }
+  ],
+  tablewith1col2rows: [
+    {
+      col: 'row1'
+    },
+    {
+      col: 'row2'
+    }
+  ]
+}
 ```
 
 These tables (`tablewith2cols1row` and `tablewith1col2rows`) will be created in SAS WORK after running `%webout(FETCH)` in your SAS service.
 
 The `request()` method also has optional parameters such as a config object and a callback login function.
 
-The response object will contain returned tables and columns.  Table names are always lowercase, and column names uppercase.

+
+### Verbose Mode
+
+Set `verbose` to `true` to enable verbose mode that logs a summary of every HTTP response. Verbose mode can be disabled by calling `disableVerboseMode` method or enabled by `enableVerboseMode` method. Verbose mode also supports `bleached` mode that disables extra colors in req/res summary. To enable `bleached` verbose mode, pass `verbose` equal to `bleached` while instantiating an instance of `RequestClient` or to `setVerboseMode` method. Verbose mode can also be enabled/disabled by `startComputeJob` method.
+
+### Session Manager
+
+To execute a script on Viya a session has to be created first which is time-consuming (~15sec). That is why a Session Manager has been created which is implementing the following logic:
+
+1. When the first session is requested, we also create one more session (hot session) for future requests. Please notice two pending POST requests to create a session within the same context: ![the first session request](./screenshots/session-manager-first-request.png)
+2. When a subsequent request for a session is received and there is a hot session available (not expired), this session is returned and an asynchronous request to create another hot session is sent. Please notice that there is a pending POST request to create a new session while a job has been already finished execution (POST request with status 201): ![subsequent session request](./screenshots/subsequent-session-request.png)
+3. When a subsequent request for a session is received and there is no available hot session, 2 requests are sent asynchronously to create a session. The first created session will be returned and another session will be reserved for future requests.
 
 ### Variable Types
 
 The SAS type (char/numeric) of the values is determined according to a set of rules:
 
-* If the values are numeric, the SAS type is numeric
-* If the values are all string, the SAS type is character
-* If the values contain a single character (a-Z + underscore + .) AND a numeric, then the SAS type is numeric (with special missing values).
-* `null` is set to either '.' or '' depending on the assigned or derived type per the above rules.  If entire column is `null` then the type will be numeric.
+- If the values are numeric, the SAS type is numeric
+- If the values are all string, the SAS type is character
+- If the values contain a single character (a-Z + underscore + .) AND a numeric, then the SAS type is numeric (with special missing values).
+- `null` is set to either '.' or '' depending on the assigned or derived type per the above rules. If entire column is `null` then the type will be numeric.
 
 The following table illustrates the formats applied to columns under various scenarios:
 
-|JS Values |SAS Format|
-|---|---|
-|'a', 'a' |$char1.|
-|0, '_' |best.|
-|'Z', 0 |best.|

 ### Variable Format Override
+
 The auto-detect functionality above is thwarted in the following scenarios:
 
-* A character column containing only `null` values (is considered numeric)
-* A numeric column containing only special missing values (is considered character)
+- A character column containing only `null` values (is considered numeric)
+- A numeric column containing only special missing values (is considered character)
 
 To cater for these scenarios, an optional array of formats can be passed along with the data to ensure that SAS will read them in correctly.

-* `serverType` - either `SAS9`, `SASVIYA` or `SASJS`.  The `SASJS` server type is for use with [sasjs/server](https://github.com/sasjs/server).

-* `debug` - if `true` then SAS Logs and extra debug information is returned.
-* `loginMechanism` - either `Default` or `Redirected`.  See [SAS Logon](#sas-logon) section.
-* `useComputeApi` - Only relevant when the serverType is `SASVIYA`. If `true` the [Compute API](#using-the-compute-api) is used.  If `false` the [JES API](#using-the-jes-api) is used.  If `null` or `undefined` the [Web](#using-jes-web-app) approach is used.
-* `contextName` - Compute context on which the requests will be called.  If missing or not provided, defaults to `Job Execution Compute context`.
-* `requestHistoryLimit` - Request history limit. Increasing this limit may affect browser performance, especially with debug (logs) enabled.  Default is 10.

To save one network request, the adapter prefetches the JOB URIs and passes them in the `__job` parameter.  Depending on your network bandwidth, it may or may not be faster than the JES Web approach.

-This approach is by far the fastest, as a result of the optimisations we have built into the adapter.  With this configuration, in the first sasjs request, we take a URI map of the services in the target folder, and create a session manager.  This manager will spawn a additional session every time a request is made. Subsequent requests will use the existing 'hot' session, if it exists.  Sessions are always deleted after every use, which actually makes this _less_ resource intensive than a typical JES web app, in which all sessions are kept alive by default for 15 minutes.
